JavaScript - How To Determine The Url For Excel File?

THIS IS NOT HOMEWORK


Hi all,

See this image:



The image represents an "entire" web page and the bright part the area currently scrolled into by the web browser.

I can get the client's screen SIZE, but I don't know how to figure how many pixels down into a page the browser happens to be.

To clarify, the distance shown as a question mark would be "zero" if the browser were scrolled all the way to the top of the page and some positive number as the browser scrolls down.

Is there any way for me to get this number (in Javascript).

What I need it for is to position a pop-up window centered left-to-right and 1/3-2/3 top to bottom on the screen REGARDLESS of where in the page the browser is scrolled.

Thanks.....

Hi,

I have a click event that changes an element from a span that acts like a text link, to a textbox that the user types in:

Code:

Event.add(area_el_rename, 'click', function(e) 
			{
				if(!currently_renaming)
				{
					area_el.innerHTML = '<textarea name=\"renaming_area\" id=\"renaming_area\" style=\"width:100px;height:10px;background-color:#DCDCDC; resize:none;font-size:8px;\"></textarea><br>';
					currently_renaming=true;
				}
			});

I am wondering if there is any way to determine if the user has clicked outside the textbox, and if so, perform an action (in my case revert back to the <span>. The solution probably doesn't need to be tied to anything. It probably just has to be something like:

if(click_outside_id("renaming_area"))
{
//do my desired action
}

HI all. How do I determine whether a variable exists in a form. I have a form called "theForm". I want to determine whether the variable "THIRD_PARTY" exists in the form and if it has been set.

I have an array of all links on a page (see var wa_links = document.links; below). How do I determine if the target of a link is set to "_blank"? I need to do this because currently with my code below, when a link has target="_blank" it ends up adding the Google Analytics code to the parent window and also opening a new window (so basically the new page opens in both the parent and target window instead of just the target window as expected).

Code:

/*Regex list of on-site domains, pipe and backslash delimited. */
var wa_onsiteDomains = /mydomain\.com|my2nddomain\.com|my3rddomain\.com|javascript/i;

//Display-friendly domain and path name
var wa_displayDomain = location.hostname.replace("www.","").toLowerCase();
var wa_displayPathname = location.pathname.toLowerCase();

/*Used to unobtrusivly add events to objects*/
function unobtrusiveAddEvent (element,event,fn) {
   var old = (element[event]) ? element[event] : function () {};
   element[event] = function () {fn(); old();};
}

function wa_crossDomainLink(i) {
	return function () { 
		var thisLink = decodeURI(wa_links[i]);
		if (typeof(_gaq) == "object")
			_gaq.push(['_link', thisLink]); return false;
	};
}

var wa_links = document.links;
if ( wa_links ){
	for(var i=0; i<wa_links.length; i++) {
		if( wa_links[i].href.match(wa_onsiteDomains) && !wa_links[i].href.match(location.hostname)){
		unobtrusiveAddEvent( wa_links[i], 'onclick' , wa_crossDomainLink(i));
		}
	}
}

With jquery I could just do something like...

Code:

if (jQuery(link).attr('target') == "_blank")

...but how do I do this in plain old JavaScript?

Thanks!

Hi everyone,

Is it possible to determine at the startup of the page if the visitor is using a computer or a phone to access the site?

I would like to make the intro process much better than a simple "click here for HTML version or click here for Flash version". I would like for it to simply redirect to the page I set it to go to depending on whether or not they're using a regular browser or a mobile browser.

How would I go about this?

Thank you all very much in advance.

greetings,

I'm unable to find solution for dreamweaver reporting syntax error with the following page:

http://www.redskyjewelry.com/test_product_detail.html

I am revamping my website so the css is not set up for this page but that's okay. I have put in the various javascripts based on the product so the page is similar to a template. The syntax error is for the second set of boxes, the bracelet length options, and specifically for line with:

form.amount.value = 6.5 inches;

from the following script--


<SCRIPT language=javascript>
function BraceletLength(form)
{

if (form.os0.value == "6.5 inches")
{
form.amount.value = 6.5 inches;
form.item_number.value = "6.5 inches";
}

if (form.os0.value == "7 inches")
{
form.amount.value = 7 inches;
form.item_number.value = "7 inches";
}

if (form.os0.value == "7.5 inches")
{
form.amount.value = 7.5 inches;
form.item_number.value = "7.5 inches";
}

if (form.os0.value == "8 inches")
{
form.amount.value = 8 inches;
form.item_number.value = "8 inches";
}


}
</SCRIPT>

I hope I have included enough information and I thank any input into this glitch I am having. I'll check back tomorrow, and thank you.

When it occurred to me that I needed to calculate this, I knew it was over my head. (although I did come up with what I thought to be a pretty clever solution involving a very complex series of arrays...) So I decided to google it. The trouble is, the solution was a little over my head too...
Sooo I hacked away at it for about an hour, and finally it worked, but on closer inspection I had made a typo from the original algorithm. So I thought I would pose the question to you all...

Is the original algorithm correct, or flawed? is my interpretation correct/flawed, or the same? I'm not really sure what I did here, but after many tests, I think I got the correct solution.

original post on http://stackoverflow.com/questions/3...ranges-overlap
Quote:
Let CondA Mean DateRange A Completely After DateRange B (True if StartA > EndB)

Let CondB Mean DateRange A Completely Before DateRange B (True if EndA < StartB)

Then Overlap exists if Neither A Nor B is true ( If one range is neither completely after the other, nor completely before the other, then they must overlap)

Now deMorgan's law, I think it is, says that

Not (A Or B) <=> Not A And Not B

Which means (StartA <= EndB) And (EndA >= StartB)

NOTE: This includes conditions where the edges overlap exactly. If you wish to exclude that, change the >= operators to >, and <= to <
And finally the test scenario that I finally got to work:
Code:

<input onclick="this.value=''" onkeyup="TEST()" id=inhour1 value=1>
<input onclick="this.value=''" onkeyup="TEST()" id=inminute1 value=1>
<br />
<input onclick="this.value=''" onkeyup="TEST()" id=outhour1 value=2>
<input onclick="this.value=''" onkeyup="TEST()" id=outminute1 value=1>
<br />
<br />
<input onclick="this.value=''" onkeyup="TEST()" id=inhour2 value=3>
<input onclick="this.value=''" onkeyup="TEST()" id=inminute2 value=1>
<br />
<input onclick="this.value=''" onkeyup="TEST()" id=outhour2 value=4>
<input onclick="this.value=''" onkeyup="TEST()" id=outminute2 value=1>

<script>
function ID(e){return document.getElementById(e)}

function TEST(){
intime1=(parseInt(ID('inhour1').value,10)*60*60)+(parseInt(ID('inminute1').value,10)*60)
intime2=(parseInt(ID('inhour2').value,10)*60*60)+(parseInt(ID('inminute2').value,10)*60)

outtime1=(parseInt(ID('outhour1').value,10)*60*60)+(parseInt(ID('outminute1').value,10)*60)
outtime2=(parseInt(ID('outhour2').value,10)*60*60)+(parseInt(ID('outminute2').value,10)*60)

comp= (intime1 <= outtime2)&&(outtime1 <= intime2) 

ID('compare').innerHTML=''
ID('compare').innerHTML+=intime1+'<br />'
ID('compare').innerHTML+=outtime1+'<br />'
ID('compare').innerHTML+=intime2+'<br />'
ID('compare').innerHTML+=outtime2+'<br />'
ID('compare').innerHTML+=comp+'<br />'

}
</script>
<button onclick="TEST()">compare</button>
<div id="compare"></div>

Any feedback would help a lot! I fear using an algorithm that I don't fully understand in production code...

I have a string of text, and starting from a particular spot (known to be a number), I want to find the length of that number.

Here's what I have: Code:

...

var start = [...predetermined...]
var end = 0;
while (!isNaN(sourceCode.charAt(start + end))){
   endCurrent++;
}
var myNum = sourceCode.substr(start, end) * 1;

So let's say var sourceCode = "alkdjabjasdsdf-53 dnalsdb..."; , startCurrent will already be at the "5" and I want to be able to extract the "53". What I have works, but it seems cumbersome...

Any advice?

I need the code for if the user enters in a code into the field for example E1 and clicks submit it'll redirect them to a certain form. And if another user entered in E2 it would redirect them to a DIFFERENT form. I hope this is the correct category of the site for me to post this. Wasn't sure if it should be here or PHP.

I have a floating div that stays at the bottom of the browser window while the user scrolls down a long page. The div reads "scroll down for more". How can I determine the current position of the div in relation to the top of the page, not the top of the browser window. I need to determine this because I would like to hide the div when the user scrolls to the top of the last page. I have looked at offsetParent, offsetHeight, scrollHeight, etc.

I have the code for everything except determining the position of the div, or the distance of the div from the top of the page.

I am allowing my customers to use a rich text editor (wysiwyg) on a jsp page to create snippets of HTML code that can be used to describe their items. When they want to add an image, table or custom tag (something we wrote), they are presented with a properties box created using javascript on the same page just below the editor. Upon clicking 'Insert' button on the properties box, I use javascript to create an HTML string with the tag information and insert the string into the edited page where the cursor was. The problem is that I can't seem to find a reliable way to know where the cursor was.

More information:

I am a C programmer who morphed to a Java programmer who knows some javascript.

The JSP page looks like this:

--------------------------------------------------------------------

Some text and text fields for some basic information


--------------------------------------------------------------------


The javascript wysiwyg editor


--------------------------------------------------------------------
The properties box (changes depending on the type of item being inserted)
--------------------------------------------------------------------

Submit button, etc. for the page (so the information can be persisted)


I have tried:

1. Seven days of searching the web for helpful hints.

2. Using a popup window to get the properties (doesn't work because in IE7, closing the popup also kills the session... I need to use some of the beans on the main window on the popup.)

3. Processing onMouseDown and onKeyDown events storing the element information in a global variable so I could use it later to know the point of insertion. (Has not been reliable and the arrow keys present real problems with where the cursor ends up as that is different from where it was pressed.)

I am frustrated because I don't seem to be gaining on the problem. I suspect it is because I have missed something very simple.

Does anyone have any ideas?

Thanks in advance.

How do I use Javascript to loop through all the spreadsheets contained in 1 excel file?

I am now at the stage where I can open the Excel file and find a value on 1 spreadsheet.
Is there any way to detect if the workbook has multiple spreadsheets and then loop through all the spreadsheets to find a value?

thanks!

Greetings!
